Scanmem is a memory scanner that allows you to find the memory address of a variable in a program by scanning the memory multiple times and seeing what has change or stayed the same since the last scan. It lets you change the variable in that memory address as well.

Thanks.  I pushed this to the master branch with commit a778f2700 after
some minor modifications.

The license was incorrect.  Parts of it are covered under the LGPLv3+,
others are under GPLv3+.

I added a copyright line for you.

I reformatted the description and made sure that there are two spaces
between sentences.  (“guix lint” should have notified you of this.)
